Make the compiler inline the hot RE2::DFA loop.

Right now the compiler does not inline the function and all branches are evaluated at each iteration of the loop.

By templating the function instead of relying on compiler heuristics to
do the constant folding, we force the compiler to create a separate
optimized copy of the code for each case.

This makes RE2 searching roughly 5 to 100% faster !
